It is a herbaceous perennial plant growing from a fleshy rhizome with stems 40–150 cm tall. The leaves are linear, 50–90 cm long and 1–2.8 cm broad. The flowers are 5–12 cm across, orange-red, with a pale central line; they are produced from early summer to late autumn on spikes of 10–20, with the individual flowers opening successively, each one only lasting one day. The fruit is a three-valved capsule 2–2.5 cm long and 1.2–1.5 cm broad which splits open at maturity to release the seeds.[1][3]
Several cultivars are known, including 'Kwanzo', where the stamens are modified into additional petals.[1] It reproduces only by stolons and division. The species H. fulva is diploid, as nearly all daylilies were until tetraploid hybrids began to be produced for their sturdiness in the 1960s.
In some parts of the United States and Canada daylilies have become a weedy or Invasive species.[4] The most common species in these areas are the Hemerocallis fulva and Hemerocallis fulva longituba.
These lilies have edible flowers. Dried or fresh they are used in Chinese, Japanese, Korean, Thai, and Vietnamese cooking, and are known as golden needles.[5].
